Construction of a simple TIMER

• Simple timer

  I'm trying to time an event as part of the larger VI, I joined the little that I want to do the timing, it is based on the example of VI. My contribution will be initially true then go wrong for a period of time (I want to measure) and then go back to true, how I want to stop the timing and stop this VI it then goes to the next step. I don't see why my timer doesn't work, but I can't see what to do to make it work. Basically when the structure of the case goes back to true it goes back to display a zero, so it always returns the value of the final timer. Is there a way I can make it store the initial value and save it and then subtract the final value?

  See you soon

• Question about the construction of cube / query performance (11.2.0.3)

  Hi, I have a stupid question on the performance of cube generation. By choosing the precalc %, is linear (or nearly linear) construction time to that? for example if you select 10% going to be 3 times faster than the selection of 30%? Also, is it fair to assume that if only 10% of the values are precalculated, an average end-user queries have to hit 3 times more data and therefore be about 3 times slower?
  
  Sorry, this on a virtual computer on your laptop, so test different configs build takes forever (I still have a load of cube really complete). Guess I should not be trying a cube Sun 15 on a virtual computer on your laptop, but trying to sell a DBA on the fact that she could improve the performance of our mini - DW.
  
  Thank you

  Aggregation based on costs (aka "Pre-computes percent") was introduced in 11.1 as a simpler alternative based on the level of aggregation. Product management dream was a linear parameter, but the complexity is quickly apparent. Which could measure the linearity against? The generation time? Time of the query? Total size of the disk? The result the balances of all of these factors, but is linear against any of them. Fortunately, behavior level percentage precompute was fairly consistent between cubes and patterns in our experience, so I can give you a rough characterization. But keep in mind that this is a guide only - you have to experience on your own scheme and a system to see what works for you. In particular, you must balance your own requirements on construction time, time of the request and the disk size.

  * 0% *-this means no precomputation at all, so all data access will be dynamic. This is the recommended setting for the top of the page partition of a cube. If, for any reason, you want to use for the scores of leaves as well, then I advise you pass a cube uncompressed.

  * 1% *-he pre-computes the smallest part of the cube that is allowed by the algorithm and would take certainly greater than 1% of the time taken by an accumulation of 100%. For partitions of leaves, it is usually best to increase the amount because you'll get much better query response time for not much more profitable in terms of disc size and the generation time. It may be a good level for the top of the page partition of a cube, but should be used with caution because the top of the page scores are often too big to pre-computes.

  * 2%-19% *-these levels does not seem to be a lot of benefits since the amount of time and the total size of the disk is almost identical to a construction of 20%, but queries are slower.

  * 20%-50% *-this range is probably the best compromise in terms of construction compared to the time of the query. The default value of the AWM is 35%, which is a good starting point. Lower it to 20% if you want a faster version and get up to 50% if you want to replace the faster queries. The setting is close to linear in this interval than outside it.

  * 51%-99% *-you should probably avoid these levels, although I've seen 60% used in practice. The reason is that while the size of the cube and the length of the construction increase rapidly, the queries do not receive proportionally faster. Indeed, you may find that queries are slower because the code spends more time swapping in the pages of the disc.

  * 100% *-this will be pre-computes all (non-NULL) cells in the cube. It may be a surprise after my advice about 51%-99%, but 100% is a reasonable level to choose. This is because the code is much simpler when you know that everything is precalculated and then stored in the disk pages.

• Slow construction BR with already transcoded media (CS6 Mac)

  Very simple BR: 1 menu with 1 button and 1 timeline. All media has been transoded with SOUL.

  Start of the generation in what appears to be a normal pace, and then during the phase of "Building Films" it slows to a crawl with 24 seconds. Screenshot attached

  

  A few THINGS:

  (1) yet still seems to work, at least it is churning away on one of my Mac Pro carrots in the activity monitor

  (2) it seems to work on the BDMV/DB/BDMV/STREAM/00001.m2ts file because this file is slow growing like

  (3) the movie in the timeline is 4.1 GB and there is already BDMV/DB/BDMV/STREAM/00003.m2ts which is 4.1 GB.

  (4) in the progress of the generation, he has already built a 4.1 GB movie

  (5) I think it is construction chronology a second time, this time to transcode the file already transcoded

  Any thoughts on this nonsense?

  OS X 10.7.5

  CS6 with all updates

  SOLVED!

  Change the length of the menu query to 10 seconds. Now everything works. Thanks for the help.

• Several incoming clones with the FGV not reentrant timer

  Hello
  I want to create a launcher of timer. So I created simple timer based on a functional global variable and tried to launch several clones of her home "timer Launcher. The thing is that the timer is not reentrant (each FGV I saw was not reentrant) and I do not know how to create such a pitcher.

  Attached image illustrates the idea. So I throw clone1 (which is some reentrant VI), in this clone I have not reentrant timer but it is not reentrant in the perspective of clone 1 only. Clone 2, I have an another timer that is not reentrant from the point of view of clone 2 incoming but from the point of view of clone 1 and so on. It is quite complicated to describe, but I hope that the photo show my problem somehow.

  Help, please

  You can do this if you make your timer pre-allocate clones-reentrant and then call by reference (a reference in every clone of the Launcher timer so that each Launcher uses a clone of separate timer).

• API calculation time expired or recording clock ticks

  Is there an API available in LabWindows to memorize the graduations or calculating time expired?

  It is necessary to use with a do while loop. I want to perform an action repeatedly to 260milliseconds in a while loop and then get out of the while loop 260 milliseconds once is in place.

  What is the best way to go about this?

  According to the precision you expect from calendar, you can move the solution most simple timer () to the more complex calls of SDI APIs.

  The simplest solution (anything but needs CVI):

  tini double;

  tini = Timer ();

  While (timer() - tini)< 0.26)="">

  doSometing ();

  }

  Advanced solution are the use of () QueryPerformanceCounter and QueryPerformanceFrequency functions SDK (). Here you will find an interesting discussion thereon. This solution involves the use of the Windows SDK available in the full versions of the CVI.

  This code should work fine:

  #include

  void yourFunction (LARGE_INTEGER t) {}

  BOOLEAN error;
  Delta LARGE_INTEGER to tini, tn,

  error = QueryPerformanceCounter (&tini);)
  If (! error) {}
  Error in manage somehow

  return;

  }
  {}
  error = QueryPerformanceCounter (&tn);)
  Delta. QuadPart = tn. QuadPart - said. QuadPart;
  If (delta. LowPart > = t.LowPart)
  break;

  doSomething ();

  } while (1);

  return;
  }

• Time stamp indicator system?

  I try to use the theme of the 'system' for my front panel, and my orders and simple digital indicators converted (from 'modern'). However, I noticed that there is no indicator of stamp simple 'time' apparent on the system > digital (or elsewhere).

  Is it one that I can't find? Or do I have to hard code it so that it displays using the theme of the system?

  Thank you

  The more trivial would be to simply use a double floating point control and set its absolute timestamp format. Then convert the type timestamp in DBL with the conversion function according to.

  If you really want to go the way of a genuine system of type control, you will need to go into the control editor, which is a bit tedious editor that shows its age of beginnings of LabVIEW and William. It you start with a classic time stamp check and replace the cosmetics with a string of system or a similar control. It takes a little time to get to know the editor control and work around his troubled behavior sometimes.

• Animate CC HTML5 Timer Error: ' Eception TypeError: cannot set property 'text' undefined '.

  Guys, I'm stuck for the third day and wonder if anyone can give me an idea what I am doing wrong. I am creating a simple timer in mode CC animate HTML5 Canvas. I found a script javascript timer job and I'm trying to fit my needs.

  I keep getting the error "Eception TypeError: cannot set the property 'text' undefined ' in the Console. For some reason I can't update dynamic text with variable of time. I've highlighted the offensive line in my code Action below.

  
  Here's all the code of the Action that I have in my file:

  -------------------------------------------------

  var time = 0;

  running of var = 0;

  This.btn_startPause.addEventListener ("click", startPause.bind (this));

  This.btn_reset.addEventListener ("click", reset.bind (this));

  function startPause() {}

  If (running == 0) {}

  running = 1;

  Increment();

  this.startPause.text = "Pause";

  } else {}

  running = 0;

  this.startPause.text = "resume";

  }

  }

  function reset() {}

  running = 0;

  time = 0;

  this.startPause.text = "Start";

  this.timeDisplay.text = "00:00";

  }

  function increment() {}

  If (running == 1) {}

  setTimeout (function () {}

  time ++;

  var minutes = Math.floor (time/10/60);

  var s = Math.floor (time/10% 60);

  If (mn < 10) {}

  min = "0" + min;

  }

  If {(dry < 10)

  seconds = '0' + dry;

  }

  Console.log (min + ":" + seconds);

  this.timeDisplay.text = minutes + ":" + seconds;

  Increment();

  (}, 100);

  }

  }

  -------------------------------------------------

  I downloaded all my files online, so you can see the error by yourself: HTML file; FLA file; and the original file working I am using.

  
  Can someone point me in the right direction? (I know, it's somewhere in the area of RTFM (Read The friendly Manual))

  Thank you!

  As suggested above, the problem is caused by an incorrect reference to 'this' itself.

  'This' store on the main timeline as a different variable and use this variable for other functions instead of 'this', or

  Replace this.timeDisplay.text by exportRoot.timeDisplay.text

• When I try to do a time lapse in lightroom, that it cut the end of the video

  I then export the video, she treats as usual. BUT when I look at this return is missing at the end of the clip. I am a student level and that I should use for my course, please help.

  Alex O'Sullivan

  So to be safe, you know what I mean, take your Lightroom changes. Export to a folder of numbered sRGB in sequence of JPEGs of reasonable size (say 3840 pixels on the long side, so you can make a 4K video) and implemented the project as in the linked video in front. You can now make a simple time-lapse direct or throw in a pan and zoom in the editing Photoshop Panel, add a title caption, bland, etc. Here is an example of a Time lapse I created in this way: Jao photo blog: The Polar Vortex - Star Wings

• Calculation of time with FormCalc

  Hello!

  I am trying to create a simple time sheet form in the designer, but things don't seem to work in the way that I expected.

  I have two time fields where users are supposed to inform the hours start and end time for a job. A third hour field must display the elapsed time.

  So, I tried to solve this problem with FormCalc:

  var interval = 0

  interval = Time2Num (endTime.formattedValue, "HH: mm")-Time2Num (startTime.formattedValue, "HH: mm")

  $.formattedValue = Num2Time (interval, "HH: mm")

  It does not work. I mean, if I inform startTime = 10:00 and endTime = 11:00, the result is 23:00. How is it?

  Now, if I inform startTime = 09:00 and endTime = 11:00, the result is 00:00.  Huh?

  Please, could someone tell me what I'm doing wrong here?

  Greetings of the season!

• Combining the timer and loop

  code

  var autoTimer:Timer = new Timer (4000, 1);

  autoTimer.addEventListener (TimerEvent.TIMER, autoSlide);

  function autoSlide(e:TimerEvent):void

  }

  }

  The idea is to load a URL (code charger not included in this) in an XML list every four seconds. The loop must not repeat the cycle until the function is complete. But he shakes down all 99 URL in a fraction of a second. I'm so bad (think)?

  Any help much appreciated.

  Thank you.

  Why don't you try just a simple timer?

  Well, if you really need a variable number as when you use a loop for example, you can use something like this:

  var waitingTime = 1000;
  var xmlListLenght = 15+1; //+1 just to remember that your xmlList starts with 0
  var timesToLoop = xmlListLenght;
  var xmlListItem = 0;
  
  var myTimer:Timer = new Timer(waitingTime, timesToLoop);
  myTimer.addEventListener("timer", timerFunction); //TimerEvent.TIMER
  myTimer.start();
  
  function timerFunction (e:TimerEvent) {
       trace(String(xmlListItem) + " working");
       xmlListItem++;
  }
  

  I hope it works for you!

• I have Chinese characters in a queue (queues make supports Unicode)?

  I am aware that there is a number of tools that allow the use of Chinese characters in LabVIEW. I have successfully built an application where I am able to switch between English and Chinese, as well as all text, buttons, screen etc multi-column list boxes are updated correctly.

  However, I do all my recording of events by using queues. When I remove one point, I want to write to a log (i.e. a ".txt" file) file, but the resulting file contains waste instead of Chinese characters.

  As an experiment, I created a simple VI who reads an array of Chinese and written text into a text file and it works fine. But, as I say, if I try to do that using queues, I just just get garbage.

  Any help would be much appreciated.

  Lee

  I don't know a lot about Unicode, but the issue could be the end of the line inserted by writing to a text file. Help for this function:

  This function adds characters depending on the platform end of line (EOL) to the elements of a table even if you right-click the function and remove the check mark next to the menu item Convert EOL .

  I changed it so that a string is constructed within a certain time a loop using a shift register and concatenate strings. In this way you write just a single strnig instead of an array of strings with the EOL. Yet once I don't know if that is still the question.

  You should also take advantage of data flow and do not use the structure of the sequence. I modified your program to do. The cluster of queue data type specification must also be a typedef.
